Description
Technical Field
[0001] The present invention belongs to the technical field of loudspeaker cone assembly, and more specifically, particularly relates to an automatic assembly device for a loudspeaker cone. Background Art
[0002] The automatic assembly equipment for speaker cones refers to a series of machinery and control systems specially designed for the automated production of speaker cones. These devices integrate a variety of automation technologies to achieve efficient, precise and repeatable production processes. By integrating these automation technologies and systems, the automatic assembly equipment for speaker cones can significantly improve production efficiency and reduce production costs while ensuring the consistency and reliability of product quality.
[0003] The existing automatic assembly equipment for speaker cones still has the following disadvantages:
[0004] 1. At present, the speaker cone is still manually loaded during the assembly process. Operators need to repeat the loading action continuously, which increases labor intensity and fatigue. With the increasing development of automation technology, manual loading seems to be backward and is not conducive to the modernization of enterprises.
[0005] 2. The automatic assembly equipment itself lacks an effective buffer structure. When the equipment encounters bumpy roads during transportation or movement, it will accelerate the wear of the assembly equipment and shorten the service life of the equipment. The damage to the equipment and components requires more frequent maintenance and replacement, increasing maintenance costs.
[0006] 3. During the assembly of the speaker cone, the adhesive between the cone and the cone frame is squeezed outwards under pressure during assembly, resulting in excess edge overflow. However, there is a lack of effective structure to handle the overflow during the assembly process, and subsequent trimming is required, which increases time and cost.
[0007] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic assembly device for a speaker cone is provided, in order to achieve a more practical purpose. Summary of the invention
[0008] In order to solve the above technical problems, the present invention provides an automatic assembly device for a speaker cone to solve the above problems.

There are two fixed rods 16, two transmission belts 23 are arranged between the card plate 6 and the conveying frame 7, two groups of rollers 18 are rotatably connected in the conveying frame 7, a connecting frame 25 is fixedly connected to the lower surface of the connecting plate 8, two strip blocks 28 are fixedly connected to the lower surface of the connecting frame 25, a fixed shaft 27 is arranged below the connecting column 9, a cutting ring 26 is fixedly connected to the annular side surface of the fixed shaft 27, two limiting rings 31 are clamped on the annular side surface of the fixed shaft 27, and limiting grooves 30 are provided on the opposite surfaces of the two strip blocks 28. The two limiting grooves 30 There are movably engaged limit blocks 34 inside, and the lower surfaces of the two pairs of connecting blocks 4 are fixedly connected with pulleys 11. The upper surface of the fixed plate 3 is provided with two slots 10, and the two slots 10 are slidably connected with the two pairs of pulleys 11 respectively. During use, the sound basin and the basin frame are accurately placed in the conveying frame 7 to ensure that they are correctly aligned. The two motors 20 are started and their output shafts will drive the gears 24 fixed thereto to rotate together. The two gears 24 will drive the two transmission belts 23 engaged therewith to rotate during the rotation process. The two transmission belts 23 will drive the remaining gears 24 to rotate together during the rotation process. The two sets of gears 24 rotate toward the opposite surfaces at the same time. The two sets of gears 24 will drive the two sets of rollers 18 fixed thereon to rotate together during the rotation process. Both sets of rollers 18 are made of rubber to increase friction. The two sets of rollers 18 will drive the sound basin and the basin frame to move together while rotating relative to each other. The two sets of rollers 18 are equidistantly arranged to effectively ensure stability during the movement process. Automatic loading ensures consistency of operation and improves production efficiency.
[0027] The two pairs of fixed blocks 17 are provided with connecting rods 13 on the back sides thereof, and the two pairs of connecting rods 13 are rotatably connected with the two groups of connecting shafts 12 respectively. Two round rods 14 are movably sleeved in the two pairs of connecting blocks 4 respectively, and two springs 15 are fixedly connected to the opposite surfaces of the two pairs of connecting blocks 4. The two springs 15 are movably sleeved with the two round rods 14 respectively. When the equipment encounters a bumpy road section during movement, the working plate 2 and the fixed plate 3 are subjected to pressure, which will drive the two pairs of connecting shafts 12 fixed thereto to move relative to each other. During the relative movement of the two groups of connecting shafts 12, the two pairs of connecting rods 13 rotatably connected thereto will be driven to be relatively squeezed. During the relative squeezing process of the two pairs of connecting rods 13, the two pairs of connecting blocks 4 will be pushed to move together.

[0028] Two blocks 21 are fixedly connected to the upper surface of the card plate 6, and the two blocks 21 are fixedly connected to the conveying frame 7. Two groups of gears 24 are arranged in the two transmission belts 23. The upper surfaces of the two groups of gears 24 are fixedly connected with output rods 22. The two groups of output rods 22 are respectively fixedly connected to the two groups of rollers 18. Adhesive is smeared between the sound basin and the basin frame. The cylinder arranged on the frame 1 is started to push the connecting column 9 to move. During the movement of the connecting column 9, the fixed shaft 27 will be driven to move together. During the downward movement of the fixed shaft 27, appropriate pressure will be applied to the sound basin to ensure good contact between the adhesive and the sound basin and the basin frame to promote bonding.
[0029] Two motors 20 are fixedly installed on the lower surface of the card plate 6, and the output shafts of the two motors 20 are fixedly connected to the two gears 24 on the left side of the two sets of gears 24, and the two motors 20 are rotatably connected with screws 29, and the two screws 29 are respectively threadedly sleeved with two limit blocks 34, and the two limit rings 31 are fixedly connected by screws.

The cutting ring 26 fits tightly with the sound basin and the basin frame. When too much adhesive is applied, the adhesive overflows during the relative squeezing of the sound basin and the basin frame. When the connecting column 9 is in the rising process, the cutting ring 26 will cut off the overflowed adhesive. By cutting off the excess adhesive, the appearance quality of the sound basin and the basin frame can be ensured, and the subsequent trimming work can be reduced, thereby effectively improving the assembly efficiency.
[0030] Working principle:
[0031] The first step is to place the basin and basin frame accurately in the conveyor frame 7 during use, ensure that they are correctly aligned, start the two motors 20, and their output shafts will drive the gears 24 fixed thereto to rotate together. The two gears 24 will drive the two transmission belts 23 connected thereto to rotate during the rotation. The two transmission belts 23 will drive the remaining gears 24 to rotate together during the rotation. The two sets of gears 24 will rotate toward opposite surfaces at the same time. The two sets of gears 24 will drive the two sets of rollers 18 fixed thereon to rotate together during the rotation. Both sets of rollers 18 are made of rubber to increase friction. The two sets of rollers 18 will drive the basin and basin frame to move together while rotating relative to each other. The two sets of rollers 18 are equidistantly arranged to effectively ensure stability during the movement. Automated loading ensures consistency in operation and improves production efficiency.
[0032] In the second step, when the equipment encounters a bumpy road section during movement, the working plate 2 and the fixed plate 3 are subjected to pressure, which will drive the two pairs of connecting shafts 12 fixed thereto to move relative to each other. During the relative movement of the two sets of connecting shafts 12, the two pairs of connecting rods 13 connected thereto in rotation will be driven to be relatively squeezed. During the relative squeezing of the two pairs of connecting rods 13, the two pairs of connecting blocks 4 will be pushed to move together. The relative movement of the two pairs of connecting blocks 4 compresses the two springs 15 for buffering. The two pairs of connecting blocks 4 are clamped with the fixed plate 3 through the pulley 11 fixed thereto to ensure the stability of the buffering. This structure can effectively absorb the impact caused by uneven road surface or emergency stop of the equipment during transportation, reduce the damage and impact to the parts inside the equipment, and extend the service life of the equipment.
[0033] In the third step, adhesive is applied between the sound basin and the basin frame, and the cylinder set on the frame 1 is started to push the connecting column 9 to move. During the movement of the connecting column 9, the fixed shaft 27 will be driven to move together. During the downward movement of the fixed shaft 27, appropriate pressure will be applied to the sound basin to ensure good contact between the adhesive and the sound basin and the basin frame to promote bonding. A cutting ring 26 is fixed on the annular side of the fixed shaft 27. The cutting ring 26 fits tightly with the sound basin and the basin frame. When too much adhesive is applied, the adhesive overflows during the relative squeezing of the sound basin and the basin frame. When the connecting column 9 is rising, the cutting ring 26 will cut off the overflowed adhesive. By cutting off the excess adhesive, the appearance quality of the sound basin and the basin frame can be ensured, and the subsequent trimming work can be reduced, thereby effectively improving the assembly efficiency.
